ERASTUS E. WINKLEY, OF LYNN, MASSACHUSETTS.

MACHINE FOR OPERATING UPON SOLES.

Application filed November 20, 1914.

To all whom it may concern:

Be it known that I, ERAsTUs E. \VINKLEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of lvfassachusetts, have invented certain new and useful Improvements in'Machines for Operating Upon Soles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a machine for operating upon shoe soles and more particularly to a machine of this character for operating upon a sole before it is incorporated in a boot or shoe.

It is customary in manufacturing certain classes of shoes to trim the flat sole to substantially the desired shape before it is incorporated in the shoe, and in connection with this rounding operation, as it is termed, it is desirable to bevel the marginal portions of the shank.

One object of the present invention is to provide a machine of this type which performs the operations of rounding the sole and skiving the shank of the sole in an improved manner and with a minimum amount of attention upon the part of the operator.

With this object in view a feature of the invention consists in the combination of sole rounding mechanism, mechanism for skiving the shank of the sole, and means for operating the rounding and skiving mechanisms automatically and in the sequence named.

A further feature contemplates in a machine of this type, mechanism for clamping a fiat sole in operative position, sole rounding mechanism, and means under the control of the operator for actuating the sole clamping mechanism and permitting the operation of the sole rounding mechanism.

A. further feature of the invention consists in the combination of sole clamping mechanism, sole rounding mechanism, means for actuating the sole rounding mechanism, and means under the control of the operator for actuating the sole clamping mechanism automatically locked in operative position until the completion of a cycle of operations by the sole rounding mechanism.

Certain of the above features are equally applicable to machines in which either the sole roundi g r kivi g ope a i ns a per Specification of Letters Patent.

formed singly, and these features are not to be considered as limited to their employment in a machine of this character, but are to be considered broadly in connection with machines of this general type.

Still further features of the invention consist in certain novel features of construction, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the accompanying description.

' In the drawings illustrating the preferred form of the invention; Figure 1 represents a. side elevation of the improved machine; Fig. 2 a top plan view of the machine shown in Fig. 1 with the clamping head removed and illustrating the skiving knives in an inoperative position to permit the operation of the rounding mechanism; Fig. 3 is a view similar to Fig. 2 illustrating the skiving knives in an operative position prior to the skiving movement; Fig. 4 is a left hand end elevation of the machine shown in Fig. 1; Fig. 5 is a detail illustrating the mechanism for controlling the operation of the skiving knives; Fig. 6 is a detail illustrating another view of the mechanism shown in Fig. 5; Fig. 7 is a right hand end elevation of the machine with the skiving mechanism and clamping head removed; Fig. 8 is a detail partly in section illustrating the mechanism for locking the operating treadle in a depressed position during the operation of the machine. Fig. 9 is a detail illustrating a plan view of one of the rotary knife carrying arms and showing the position of the knife in operative relation to the sole; Fig. 10 is a side elevation of the arm shown in Fig. 9; Fig. 11 is an end elevation of the arm shown in Fig. '9 and illustrating the manner in'which the knife operates upon a sole; and Fig. 12 is a detail illustrating the rotary knife carrying head.

The illustrated embodiment of the invention shows a rounding machine of the general type disclosed in the patents to Mayo, No. 882,009, March 17 1908, and No. 1,091,071, March 2a, 1914. This machine comprises a standard 1 carrying an overhanging arm 2 upon the outer end of which is supported a clamping head indicated at 1. This clamping head is actuated in the usual manner through a lever 5 fulcrumed upon the arm at 6 and connected with an stationary pattern connected to the standard 1 through a column 12. The" sole is trimmed by a movable roundingmkn fe which is caused to travel completely around knife 14 is support-ed upon the inner end of an arm16 located upon the knife carrler 17. The knife carrier is' slidin'glymounted-on a rotary table lSjourn'aled upon thecolumn and operated-in the usual manner from the driving shaft through the intermeshing beveled gears 19 and 20. The-operation of the rounding' mechanisln is controlled-by a shipper handle 22' which permits the connec- 4 tion of the 'drive pulley-23 with the drive shaft 'to "cause'the' rotation ofthe table 18. After the table has made one complete rotation the driving mechanism is automatlcally disconnected and the brake indicated at 25 is applied through the engagement of a tripping "lever 26' with a-trip 27 carr1ed by the rotary table. It is 'desirable in connection 'with this type ofmachineto prev n operation of the'rounding or'other mechanism untilthe sole has been firmly clamped in position. To'thisend mechanism is provided for normally preventing the'operation of the actuating meehanismand this locking mechanism is-eonnected with the'clamping head in such a manner that the operation of the rounding mechanism is permitted when the clamping head'is moved into an operative position. A-b ell crank is fulcrumed at 30 upon" the machine frame and is provided with anarm 81'connected to the treadle 7 by a link 32.

The second arm 33 of the'bell crank is connected to a latch rod 85' having a. tooth 36 engaging'withi a cooperating tooth'37 formed uponaslide rod 3 8. The end of the rod 38 is normally positioned in front of one arml40 of abell crank fulcrumed at 41 and. having its second arm 42 connected with the: shipper handle through a link 43 "and an arm 44 formed integrally with the fshipp'er handle. m'ally'prevents a movement of .the shipper handle to start. the sole roundingmechanism, but upon a depression of the treadle the slide rod38 is 'moved'out ofithe path of This construction northearm 4O through the above described eonspringlj47p This permits the return of the ."slide rod '38 to its initial position under the action of the" spring 45, as will be obvious to those skilled in the art.

- sitioning of a new The shank skiving mechanism is supported upon an arm 50 projecting from the standard 1 and the skiving knives are mounted upon a knife carrying head 52 which is slidingly supported upon parallel guide rods 53 and 54 secured upon the arm the edge-ofthe sole and is guided by engage- V ment with the pattern10. The roundlng 50. Two skiving knives are employed, each operating simultaneously upon opposite margins of the sole and each knife indicated at 55 is supported upon the outer end of a knife carrying arm 56 fulcrumed upon the head 52' and controlled during the length- -wise-movements of the head to cause the -'=knives to operate properly upon the sole.

'During the outwardmovement of the head the knlves are retalned out of engagement 'with the sole by arms 57 extending rearwardly from the knife carrying arms and contacting with stationary cam surfaces indic'ated at 59. As the knife carrying head is moved-forward to bring the knives into an operative position the free ends of the arms '57 ride first along the cam plates (50, then on to the pivoted cam-levers 61, which are normally retained in the position shown clearly in Fig. 3, and-finally on to the stationary cam plates 62. On the return movement of the head the arms 57 are permitted to pass behind the-cam levers 61, as shown clearly in Fig- '3, and allow the skiving knives to follow the contour of the pattern andskive out the margins of the sole. The knives are normally moved together into an operative position by tension springs ,63 which connect the free ends of arms 64 projecting rearwardly from the knife carrying arms 56 Withthe head 52. The mechanism for" controlling 'and guiding the movements ofthe knife carrying arms is substantially similar to that shownand described in the co-pending application of -VVinkley, N o.

' 606 ,1045 filed November 2, 1914, and in consequence, has been only briefly described herein.

' It is customary in rounding machines of this type to automatically stop the mechanism with the rounding knife positioned at thetoe in order to permit the convenient removal of the sole and at the same time cause the knife to act as a gage for the posole blank in the machine. In the present invention the skiving mechanism acts conjointly with the rounding mechanism and upon the approach of the rounding-' knife toward the toe upon the completion of its movement around the sole the skiving knives are automatically moved forward into an operative position. When "the rounding knife has completed its operation the skiving knives are ready to commence the rearward or skiving movement, thus causingthe two-operations to be performed without interference and in a minimum of time. The skiving mechanism is operated" by a counter-Shaft 65 operated from the drive pulley 23 through pulleys 66 and 67 and a connecting belt. The countershaft 65 operates a cam shaft 7 0 through intermeshing worm gears 71 and 72. The proper traversing movements are imparted directly to the knife carrying head by an actuating lever 73 fulcrumed upon the arm at 74 and having its upper end pivoted to the knife carrying head. The actuating lever is operatively connected with a rotary path cam 75 through an arm 76 connected to the lever and having its free end engaging with the cam.

The movements of the actuating cam are automatically controlled to start the cam at the proper time to cause it to make one complete rotation and stop the cam at the completion of the skiving operation. To this end the driving pulley 67 is connected to the counter-shaft 65 through a Horton clutch indicated at 80. The clutch is controlled automatically by a rocker arm 81 supported upon one end of the rock shaft 82, as shown clearly in Fig. 3, and operating in the usual manner to connect or disconnect the clutch through the engagement of a tooth 83 with a lug 84: formed upon a part of the clutch. The opposite end of the rock shaft 82 carries a flat arm 85 which is actuated at predetermined intervals to lift the arm 81 and permit the operation of the clutch in the direction of the arrow in Fig. 4;. The movements of the arm 85 are imparted by a lever 87 fulcrumed loosely upon one end of the shaft 82 and having one end engaging with the face of a rotary cam 90 secured to the under side of the rotary table 18, The initial movement of the cam mem ber 90 permits the inner end of the lever 87 to be swung upwardly by a tension spring 91, allowing a pin 92 slidingly supported upon the arm 85 to be moved beneath a projection 93 formed upon the lever 87. The pin 92 is normally projected into the position shown in Fig. 5 by a spring 95. It will be observed from an inspection of Figs. 2 and 4: that after approximately one half a revolution of the table 18 the lever 87 is again depressed by the cam 90 carrying the arm 85 with it through the pin 92 and projection 93 and at the same time raising the arm 81 to cause the connection of the automatically disconnected. To this end the pin 92 is provided with a disconnecting lever 96 fulcrumed upon the arm 85 at 97 and having its free end located in the path of a lug 98 projecting from the face of the worm gear 71. When the disconnecting lever is oscillated to remove the pin 92 from beneath the projection 93 a spring 100 serves to oscillate the rock shaft and return the arm 81 to the position shown in Fig. 4:, in which position the tooth 83 engages with the lug 8 1 and disconnects the Horton clutch at the completion of a cycle of operations.

It is desirable after the sole has been clamped in position by the operator to provide means for locking the clamping mechanism in operative position until the machine has stopped and to furthermore provide means for automatically releasing the clamping head upon the completion of a cycle of operations. To this end the treadle 7 is normally locked in a depressed or 013- erative position by a sliding stud 101 pivoted to the treadle and passing through a box 102 which is provided with a recess containing a roll 103 bearing against the face of the stud 101 and normally pressed up by a spring 10 1 to grip the stud in the usual manner and prevent an upward movement. The clutch is released automatically to permit the elevation of the treadle under the action of the spring 104 connected to the clamping head. This is accomplished by the engagement of a lug 105 formed upon the periphery of the path cam 75 with an arm 106 fulcrumed upon the frame at 107, as shown clearly in Fig. 1 and connected with a lever 108 through a link 109. The lever 108 is normally moved in a direction to maintain the arm 106 in engagement with the peripheral surface of the path cam by a tension spring 110 and the free end of the lever is connected through a link 111 to an oscillatory dog 112 which actuates a releasing block 113 to depress the locking roll 103 against the action of the spring and release the clutch.

In order to improve the cutting action it is desirable to provide rotary cutting knives which are positively operated at a suitable rate of speed. To this end each skiving knife indicated at 55 consists of a rotary head 115 to which are secured a series of cutting blades 116 by suitable threaded fastenings 117. The cutting blades are provided with beveled cutting faces to skive the sole as shown in Fig. 11 and the rotary knife head is mounted upon the lower end of a shaft 119 journaled in the outer end of the knife carrying arm 56. The upper end of the knife shaft 119 is provided with agear 120 which meshes with a large driving gear 121 journaled upon the knife carrying arm. The driving gear 121 is operated through a driving sprocket 122, chain 123 and driving sprocket 124 journaled at the fulcrum of the lmife' carrying arm 56. Each of the driving sprockets 124 is operated by a spiral gear 126 mounted upon a drive shaft 127 journaled in the head-52. The shaft 127 is'provided with a drive pulley 128 which is operated in any suitable manner to constantly rotate the skiving knives during the back and forth traverse of the knife carrying head. As shown clearly in Figs. 1 and 3, each driving chain is inclosed by a casing 130, the i-nterm'eshing gears by a casing 131, and the rotary skiving knife by a guard or casing 133'. The knife guard, as-shown clearly in Figs. 9 and 10 comprises a curved shield fulcrumed-upon the knife carrying arm at 135 and having its free end caused to follow the contour of the sole by a coil spring 136. The inward movement of the curved shield 133 is limited by the contact of a stop screw 138 with the 1 face of the knife carrying arm, as shown in Fig. 9. The rotary knife is retained in engagement withthe surface of the sole during the cutting operation and is guided to follow the contour of the pattern by a combined guide member and presser foot indicated at 140 which has a guiding face arranged to engage with the side of the pattern, as shown clearly in Fig. 11, and a portion 141 which is arranged to project beneath-the pattern and retain the knife in engagement with the surface of the sole. The knife may be adjusted relative to the presser' foot 141 to vary the depth of cut through the provision of a separable dovetailed connection indicated at 142*. The knife is firmly clamped in any adjusted position by a set screw 143.

While it is preferred to employ the specific construction and arrangement of parts shown and described, it will be understood that-this constructionand arrangement is not essential except so far as specified in the claims, and may be changed 'or modified withoutdeparting from the broader features of the invention.
